What Does It Mean When We Store Enough Rare Metal
Rare metal gets its name because of it little amount in nature. However, what really makes us treasure
them is not because of its amount, but its position in modern industry.
Rare metal can be divided into five kinds, which are rare light metal, rare refractory metal, rare distributed
metal, rare earth metal and rare radioactive metal. Most of them are of special quality and are widely
used in electrical industry, chemical industry, ceramic industry, atomic industry, rocketry, etc.
Due to the particularity of rare metal, it has strict production engineering and storage requirement. For
example, titanium, zirconium and vanadium are dispersedly distributed and exists with other metals, so
people often need to use special method to gain them. What’ more, since many kinds of rare metal are of
radiation and pollution, they are required to store indoor warehouse and to be far away from residential
area, school and hospital.
It is because of its extraordinary function and its limited storage, rare metal are Strategic resources in
certain extent. Many countries limit to mine and export rare metal. For example, America has purchased
one third tantalum powder. Although China has rich resource, but for quite some time, we indulge mine
and export, which cause great lose for ourselves.
